NES controller now controls cursor

What a change for the once-mighty NES controller, where it used to control Mario and Samus who saved their respective worlds, all the controller does now is control the cursor on your computer display (not to mention accelerating your path towards RSI due to its obviously unergonomic nature). This DIY project replaces the innards of a NES controller with that of an optical mouse, so you’ll have to invest a fair bit and have a decent amount of technical know-how before embarking upon this project. Definitely one of the fanboys.
